Methane is a potent greenhouse gas that contributes to global warming and climate change. It is produced when organic waste decomposes anaerobically (without oxygen) in landfills1. Construction and demolition waste, which accounts for about a third of all solid waste generated in the world2, often contains a large amount of organic materials, such as wood, paper, and food waste1. Therefore, disposal of solid waste from building construction and operations in landfills has a substantial effect on methane emissions13. Incineration of solid waste also produces greenhouse gases, such as carbon dioxide, carbon monoxide, and hydrochloric acid, but at lower levels than landfilling45. Volatile organic compounds (VOCs) are not greenhouse gases, but they can react with other pollutants to form ozone, which is a greenhouse gas and a health hazard4.
